How many solutions does the system have?
RUDIKE [14]

For this case we have the following system of equations:

21x + 6y = 42\\7x + 2y = 14

We multiply the second equation by -3:

-21x-6y = -42

Thus, we observe that the second equation is equivalent to the first, if we add both we get:

21x-21x + 6y-6y = 42-42\\0 = 0

The equality is fulfilled. The lines are on top of each other.

Answer:

Infinite solutions
